Tuff Spas Air Induction Failure

Air bubbles are not coming from the jets even when air controls are open.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Closed or clogged air control valves, Blocked venturi air lines, Waterlogged Tuff Spas air check valve, Debris in jet venturi ports

Safety: Turn off power before disassembling any valves or jets.

Step 1 – Verify air controls: Turn the air control knobs on the spa rim fully open.
Step 2 – Inspect air intakes: Locate the air intake openings under the cabinet and ensure they are not blocked by insulation or debris.
Step 3 – Clean jets: Remove a few jets and inspect the venturi ports for scale or debris; clean as needed.

If air still does not mix with water, the internal air check valve or plumbing may need inspection and replacement by a technician.
